Title: Improvements in or relating to the manufacture of concrete articles
IPC: B28B1/08
Filed: 1939-07-31
Abstract: 533,216. Moulding concrete; moulds. WITHEROW. W. P. July 31, 1939, No. 22194. Convention date, Aug. 5, 1938. [Class 87 (ii)] In making concrete articles, a concrete mix is deposited in a mould, heat is applied to drive off surplus water and the articles are vibrated or compressed to remove voids. Moulding, curing and ageing are preferably carried out in a single building 110, 111. A vehicle 115 delivers mixed concrete to gang moulds 119 which are vibrated to compact the concrete in the moulds, which are then heated by passing steam through pipes 121 in water in a tank 120, causing partial curing. The moulded articles are then subjected to vibration and compression. To effect complete curing the articles are deposited in an open bottomed box 123 over a steam-heated water tank 124. The articles are then separated from the moulds, piled in skips 126 and dipped in a tank 127 of cold water, which may contain colouring, sealing and hardening media, after which they are piled at 129 to mature. The Specification as open to inspection under Sect. 91, comprises a plurality of moulds, Figs. 2 (Cancelled) and 7 (Cancelled), which are defined by removable pallets 40, side plates 44 of the pallet supports 43, the side and end plates 15 of the shell and the partitions 30 between the moulds. Steam for heating the concrete is supplied beneath the mould compartments After partial curing the pallet supports and pallets are raised by jacks 52, the cores 27 being allowed to move upwardly to a limited extent Thereafter the pallet supports and the moulded blocks are removed for storage during ageing As shown in Fig. 14 (Cancelled) shells 62 may be resiliently mounted on framework 63 by springs 64 to permit vibration. This subjectmatter does not appear in the Specification as accepted.

IPC: C11C3/00
Filed: 1931-08-06
Abstract: Unsaturated oils, fats and the corresponding acids, having more than ten carbon atoms are sulphonated by first treating them with a sulphuric acid derivative in which single or double substitution of the hydrogen atoms has been effected by means of alkyl, aryl, acyl or aralkyl groups and then with an acid condensing agent. In examples: (1) castor oil is treated with n-butylsulphuric acid, dimethylsulphate or acetylsulphuric acid and then with chlorsulphonic acid; (2) olive oil is treated with glycerine trisulphuric acid and then with chlorsulphonic acid; (3) castor oil is treated with acetylsulphuric acid and chlorsulphonic acid and aluminium chloride subsequently introduced; (4) castor oil is treated with chloracetylsulphuric acid and phosphoruspentachloride afterwards added.  The products are stated to be wetting agents and may be used for the production of emulsions and pastes in the textile industry. Reference is made to use of the products after neutralization as a reviving oil in cotton dyeing.  Thionyl and sulphuryl chlorides and phosphorus pentoxide and oxychloride are mentioned as acid condensing agents. Specification 347,592 is referred to.ALSO:Unsaturated oils, fats and the corresponding acids, having more than ten carbon atoms, are sulphonated by first treating them with a sulphuric acid derivative in which single or double substitution of the hydrogen atoms has been effected by means of alkyl, aryl, acyl or aralkyl groups and then with an acid condensing agent.

Patent GB-1090073-A (GB)
Title: Improvements in or relating to photosensitive devices
Inventor: CASSMAN HARRY
IPC: C23C14/06
Filed: 1963-06-06
Abstract: A photo-sensitive device contains a porous layer of photo-conductive material in contact with a semi-porous layer of photo-conductive material. In a vidicon-type camera tube this composite layer may be formed directly on the transparent signal electrode or on an intervening layer such as a thin solid layer of the same or a different photo-conductive material.  As particularly described a 1" diameter disc of glass or quartz, which is to be the face-plate of a camera tube, is provided with a translucent electrode by spraying its hot surface with a solution of a tin salt.  The disc is placed at 25-40mm from a boat containing antimony trisulphide and a 1-2m  layer of the sulphide vapour deposited in an argon atmosphere having a pressure of 1mm Hg.  Since the mean fee path of the antimony trisulphide is about 0.05mm the molecules are able to form relatively large aggregates before reaching the substrate so that a porous layer is formed.  A 0.5 m  layer of the sulphide is then deposited at an argon pressure of 0.03mm Hg. in which the mean fee path of the photo-conductor is about 1.5mm.  Smaller aggregates are thus formed and a semi-porous layer is produced.  During production of the composite photo-conductive layer a mask is used to prevent deposition around a peripheral zone of the disc where it is to be bonded to the tube.  The invention may also be applied to tubes when the composite layer is deposited in situ.

Abstract: 594,781. Dielectric heating. JABLONSKY, B. Nov. 22, 1944, No. 23213. Addition to 566,927. [Class 39 (iii)] In the dielectric heating of an article 1 having portions of different average thickness, two electrodes 81 and 9<1> are connected across a high-frequency generator 41 and arranged on one side of the article, each facing a different portion. An intermediary unconnected electrode 10<1> faces both portions on the opposite side. For example, a stack of wood laminae 11 interleaved with a binder, is moulded between dies 15, 16 to form an air-screw blade. The electrodes 8<1>, 9<1>, 10<1> are situated between the laminµ 11 and the dies, and may be loose or carried by the dies, The generator 41 is coupled through a resonant circuit to the electrode 8<1> and to earth. The electrode 9<1> is earthed. These connections may be made before or after dies are clamped and removed from a press 12. Insulation between the electrodes may be provided by parts of the dies or by insulating strips folded over the edges of the electrodes. Larger articles can be subdivided to form the dielectrics of more than two series-connected capacitors. The heat developed in the different portions may be adjusted relatively by varying the electrode areas. Such adjustment can be made to compensate for portions having different dielectric characteristics. Specification 573,021 is referred to.
